To all whom t may concern:

Be it known that I, FREDERICK G. SAR- GENT, a citizen of the United States, residing at IVestford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Conveying Device for Wool- Driers, of which the following is a specification.

The principal objects of the invention are to provide a simple device in which the teeth are fixed on their supports so that no means has to be provided for moving the individual teeth, thus materially simplifying the mechanism involved; also to provide improved means for supporting the reciprocating element, an improved damper operating device, and other features of construction and combinations of parts aswill appear.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a side elevation of a preferred embodiment of the invention showing it as applied to a wool drier;

ig. 2 is a sectionalv view of the same on the line 2-2 of Fig. 1, and

Fig. 3 is a longitudinal elevation on enlarged scale of the reciprocating pin support and means for holding it in position.

The invention is shown as applied to a drier 10 having the usual blowers 11 and provided with a slatted stock support 12 mounted on fixed transverse supporting members 9. This is shown in this case as horizontal. The driving mechanism need not be described in detail, but gearing and pulleys at 13 are shown provided with a crank 14 for driving a pitman 15 which is connected with a cross bar 16. A duplicate set of driving mechanism is preferably located at the other side of the wool chamber also, or at least some means for insuring parallel motion.

This cross bar 16 is only one of a plurality of cross bars which are all secured to a pair of longitudinal bars in the form of inverted channel irons 17. These parts 16 and 17 in this case constitute a reciprocating frame. It is supported by a pair of stationary channel bars 18 the other side up and iXed Yto the inside of the machine and to brackets 23 carried by the members 9. In the space between the two channel bars 17 `the slot and with a and 18 on each side are a plurality of free unattached rollers 19.

The cross bars 16 carry a plurality of longitudinal bars 20, each of which is provided with a plurality of forwardly inclined fixed teeth 2l. The reciprocation of this frame 1 6-17 by the gearing results, of course, 1n the horizontal reciprocation of these teeth which are all fixed relatively to each other and which have no up and down motion. They stick up through the slots in the slatted support 12 so as to engage the wool or other material thereon. Beingfinclmed they force it in one direction on the forward motion and have no material effect upon it upon the backward motion, except to loosen 1t up.

From the blowers the air circulates in the direction of the arrows shown in Fig. 2. For the purpose of regulating the draft down through the ber on the support 12 a by-pass is provided in the form of a hollow metallic structure 25, one for each blower. Each of these structures is provided with a damper 26 on a shaft 27 having a handle 28 thereon extending out through the side of the device to which it is applied. This handle has a pin 29 which moves in a curved slot 30. This pin is provided with a head on the back located inside thumb-nut 31 on the front to secure it in any adjusted position. In this way the amount of draft through this member is regulated and any desired proportion of the current forced to go through the wool. This is desirable because the current is sometimes strong enough to hold the wool down on the support 12 and prevent its being fed along properly and also to prevent its being exposed to the air throughout mass of ber.

Although I have illustrated and described only a single form of the invention, I am aware of the fact that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claim. Therefore I do not wish to be limited to all the details of construction herein shown and described, but what I do claim is In a drier for fibrous materials, the combination of a Xed supporting floor for the stockuhaving a series of. parallelrnarrow slots therethrough, a pair of reciprocable longitudinal bars, cross bars connecting them to consitute a Vsupporjing iframe, rneansdfor confining the frame' to la reciprocating motion in a plane, a series of longitudinal bars carried by the cross bars,eaehfbeingflocated under one of said slots, and forwardly nylined teeth xecl on' theilastenreritioned bars and projecting up through said slots 10 throughout the entire.v operationoiihebars j to :i'levelabovethioon 'FREDERICK G.
